I have checked the size list and I am astonished at the tiny sizes it is such a shame for I would love to buy this shirt but there is no way in hell I am going to get a 27 inch wide t-shirt over my chest.

DragonoftheArts: I was curious about the sizing as well, since I would usually wear a Medium. I contacted the Help Desk and asked them to clarify the sizing chart to me. She said instead of measuring all the way around, the measurements only regard measuring from armpit to armpit. I hope this helps. :) Everyone needs this shirt.
